A self-healing network on-board a vehicle includes multiple wireless devices that are directly and communicatively interconnected via communications backbone(s). One of devices is collectively determined by the other devices to be a lead device of the network, and therefore establishes a wireless link (e.g., an only wireless link) communicatively connecting any of the self-healing network devices to other devices/servers on-board the vehicle and external to the network. Passenger-consumable content may be delivered between any device of the self-healing network and the other on-board, external devices via the lead wireless device, its established wireless link, and the communications backbone(s). Any wireless device of the self-healing network may serve as a hot spare for the lead wireless device, so that the self-healing network may automatically reconfigure to mitigate and recover from faults, e.g., by automatically forming multiple, mutually exclusive sub-self-healing networks, each of which has its own cooperatively selected lead wireless device.
